To all whom it may concem:

Be it known that I, MYERS A. GARRE'I'I, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Air Moisteners and Dust Arr-esters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichv it appertains,'to make and use same.

'-The object of my invention is twofold, to wit: the provision of an effective air moistener or humidifier for the air of rooms heated by steam or hot water through the.

of health and cleanliness, are well known and need not be specified.

The invention consists in certain novelties of construction and in the,combination of parts as herein set forth and claimed.

The accompanying drawing illustrates an example of the embodiment of the invention, the parts being constructed and combined according to one of the best methods of procedure I have so far devised for the purpose. J

Figure 1 is anend view in elevation,

showing a radiator-with the improved air moistener and dust arrester supported thereupon.

Figure 2 is a front view in elevation of Figure 1, the right hand portion of the moistenerbeing broken away to show the construction.

Figu elevationof the upper art of Figure 1.

Figure 4 is a top p an view of part of Figure 1 and on the same scale as Figure 3.

Figure 5 is a top plan view of the perforated, removable cover, the right hand end being broken away to show the location of.

the frame and its covering.

Referring to the figures of the drawing, the

numeral 1 designates a steam or hot water radiator of any type; 2, a water tank or reservoir preferably made of sheet metal, rectangular in cross section, closed at the botre 3 is an enlarged sectional view in,

.tom andopen at the top; 3, 3, metallic hooks or curved metallic bars secured-at their rear ends to the vertical wall of the tank by rivets or otherwise, their front ends being extended over and resting upon the connections which unite the sections of the raf diator; and 4 is a metallic frame for supporting the removable cover carrying anair moistener and dust arrester proper.

The frame 4 comprises an angle iron 5 having its vertical flange extended about and riveted to the open end of the-water tank on' three sides thereof, and the opposite free ends 6 of said angle iron are of sufiicientlength to extend over the top of the radiator; an angle iron 7 having its horizontal flange secured to thehorizontal flange of the angle iron 5 and extended entirely around the top of the radiator, the same being rectangular in shape; and an ornamental apron 8 secured at its top edge tothe vertical flange 0f the angle iron 7 and its lower edge extendlng downwardly over the top of the radiator so as to conceal the top parts there- 1 of at the ends and front; otherwise stated,

the ornamental apron laps over the top,

front and ends of the radiator.

The projecting .ends of 'the angle iron 5 may rest upon the sections of the radiator, and, being securely riveted to the top edge of the tank on three sides thereof, may aid in supporting the tank and holding it in proper position; in fact, if the frame 4 be strong enough, it may support the water tank and the apron hold it in place.

. A'sheet metal cover 9 rectangular in plan and perforated as shown has it's longitudinal edges turned to form recesses 10, 10, the cover, when in position, resting upon the horizontal flange of the angle iron -7, as shown by 'Figure 3.

A rectangular skeleton frame 11 over which is slipped abaflie cloth 12 of bag shape provides two parallel layers of cloth spaced apart for absorbing the watery vapor evaporated from the tank and for arresting the dust in the air when the latter passes through the cloth. The frame 11 is supported at its edges in the recesses 10, 10 of the coverand it can be inserted and withdrawn endwise relative to the cover when one end of the cover is raised.

Figure 1 shows the radiator spaced a slight distance from a partition 13 and baseboard 14 with the tank located between radiator as shown, the operation is as"fol-. lows: The water becomlng heated passes in the form of vapor upwardl to. the baiile cloth which becomes moistene as it retains some of the vapor. vapor mingled with the hot air arising The remainder of the for water having an open top; a'housing including an angle iron 7 extending entirely around the! housing, and an. apron, said housing being secured to the top of the tank so as to'projeot at right angles from around the radiator and beneath the apron one sideof the body of the tank far enough passes through the holes in the cover to the atmosphere of the room which is molstened thereby. I

It is well known that the air in a room heated with steam-or hot water through the medium of a radiator when it comes in contact with the hot radiator ascends or rises, inasmuch as heated air is lighter than cold air, and then becomes diffused throu hout theair of the room, a constant circua.- tion or movement of the air thus being maintained. As is well known, air in a room carries dust which is evidenced by its deposition upon the walls and furnishings of the room. 1

A radiator provided with my appliance obviously will remove the greater part of the dust and light particles of matter held in suspension by the air in a room. The heated air ascending through the open spaces between the radiator sections and beneath the apron can escape only by passing through the moistened baflie cloth and out through the openings in the cover, and the reater part of the dust carried thereby will fie caught and retained by the moist baffle cloth. I

As the dust laden air repeatedly becomes heated and passes through the baffle cloth nearly all the dust is finally removed therefrom, leaving none to settle on the walls and furnishings, consequently the task of dusting is thereby obviated. v

, From the foregoing description taken in connection with the drawing it is clear that I have provided a means for not only moistening the air in a room to the desired degree of humidity necessary to health, but have also pro'videdin connection therewith means for the efiective removal of dust and foreign matter from the air which, when present, is drawn into the lungs with delto cover-the top of a radiator; a removable cover with a perforated top; supported upon one flange of the said angle iron and held in position by the other flange of the angle 1 iron; and a; dust arrester located at the under surface of the cover, said arrester being supported by the cover and. bodily re movable therefrom. v y

2. The combination in a 'device of the character described'for radiators, of a tank for holding water having an open top, a frame secured to the tank at the top thereof and extending substantially at right angles to the tank? so the frame will engage the top of a radiator and support the tank, a removable cover with openings carried by the frame, and a dust arresting means carried byfand removable withthe cover.

3. The subject-matter of claim 2 with the addition of an apron in connection with the frame which apron when the device is in use extendsvover the top of a radiator and confines and deflects the ascending air,

through the dust arresting means.

4:. The combination in a device of the character described for radiators, of a tank for holding water having an open top; a frame secured'to the tank at the top thereof and extending substantially at right angles to the body of the tank so the frame will overlap the top of the radiator when in position; a removable cover with openings carried by the frame; a dust arresting means MYnRs aqeanan'rr.
